The Kaiyukan is located in Osaka that boasts one of the biggest public aquariums around the world. They have a huge walk-around tank in the center that displays many habitats like whales, sharks, schools of fish all in one area.



If I remember correctly, the entrance fee is 2000YEN which gains you entry into the aquarium where you can stay as long as you want. Besides the large main tank, if you go in the winter season, there are usually penguins outside with snow that the public are allowed to touch and take photos with.


There is also a huge ferris wheel which you have to pay 700YEN to ride on and it shows you a top view of the area which is truly amazing. So if you are in Osaka, be sure to check it out!
